Maybe pain is making me grumpy. Just had my diazepam and feel better now.
How about a refundable deposit for appointments to encourage people to keep them. People needing repeat appointments for chronic conditions could be exempt like for prescriptions.
Repeated timewasters at A&e could be banned (no that might be harsh and dangerous) or charged for visits.
There must be some way to improve it rather than messing with the whole system like Dave wants to.
